Re: HAMMER: you can mount_hammer a UFS that was a hammer fs before

   Well, this is basically simply due to the fact that the volume headers
   are in different places and HAMMER and UFS's initial data layout winds
   up being non-conflicting.  But clearly it isn't going to stay that way
   for long.

   It's a fun exercise and we should probably adjust newfs for UFS and HAMMER
   to clean out a few extra megabytes at the beginning of the partition to
   ensure that any prior volume header is overwritten, but it isn't really
   a bug per-say.  The filesystem type in the partition editor is the more
   definitive information source.
